1. Introduction. Gallium (Ga), a soft and silvery-blue metal, was discovered in 1875 by the French chemist Paul-Émile Lecoq de Boisbaudran (Moskalyk, 2003).With an average crustal abundance of 17 ppm, Ga is considered a trace metal (Redlinger et al., 2015).This element exhibits an extraordinarily wide temperature range in the liquid state due to its low melting point (302.98 K) and …

There are no gallium mines because the concentration of gallium in ores is very low. Gallium is obtained as a byproduct of aluminium [ Box 3 ] and zinc smelting and is used to manufacture semiconductors, which are used in many electronic devices, with 10 times more gallium used in current smart phones relative to older models.

Most gallium is produced as a byproduct of processing bauxite, and the remainder is produced from zinc-processing residues. The average gallium content of bauxite is 50 parts per million. U.S. bauxite deposits consist mainly of subeconomic resources that are not generally suitable for alumina production owing to their high silica content.

Gallium rarely occurs in minerals except in trace amounts. Bauxite and the mineral sphalerite, as well as coal, often contain gallium as an impurity. No gallium is mined; it is obtained as a by-product of mining and processing other metals, notably aluminum, zinc and copper, and is produced in any nation that produces these metals.

Globally, primary gallium is recovered as a byproduct of processing bauxite and zinc ores. One company in Utah recovered and refined high-purity gallium from imported primary low-purity gallium metal and new scrap. Imports of gallium metal and gallium arsenide (GaAs) wafers were valued at about $1 million and $150 million, respectively.

Mining minerals for the sole extraction of Ga is not economical due to the low concentration of Ga. Accordingly, Ga is mainly recovered as a by-product from the processing of minerals. The current main commercial resources of Ga are Bayer liquor and zinc residue, which contribute to nearly all of the worldwide Ga production.
